Chun wouldn't say what drugs they used. He said no players or students were involved, and the incident happened off campus.

Pelini apologized in a statement "for exercising poor judgment."

Chun said offensive coordinator Brian Wright will take over on an interim basis.

"We have an obligation to put our students in the best possible position to succeed," Chun told WPBF 25 News. "This does not do that, but we're managing the mistakes of others. We're moving forward as a university, and we're going to come out a strong athletic program, a stronger football program and a stronger university."

Pelini was in his second season with the Owls. He was hired to succeed Howard Schnellenberger in December 2011 after four seasons as an assistant coach under his brother, Bo Pelini, at Nebraska.

The Owls have compiled a 5-15 record under the elder Pelini, including a 2-6 mark this season.
